Question

What is the sum of all integer value of n for which n^2+19n+92

Answer 1

Answer:

-19

Step-by-step explanation:

n²+19n+92

here a=1 , b=19 , c=92

It's a quadratic equation so it has maximum two roots.

Let two roots are

$\alpha \: and \: \beta \\ so \: \alpha + \beta = \frac{ - b}{a} = \frac{-19}{1 } = -19$

so the sum of all integer value of n= -19
